“…Blue light might also contribute to visual fatigue, but it remains unclear how significant this factor is since little research has been conducted, especially with HMDs (Heo et al 2017;Lawrenson et al 2017;Priya and Subramaniyam 2020;Tu et al 2021). Continuous (chronic) exposure to blue light might damage the retina (Ahmed et al 2018).…”

This narrative review synthesizes and introduces 386 previous works about virtual reality-induced symptoms and effects by focusing on cybersickness, visual fatigue, muscle fatigue, acute stress, and mental overload. Usually, these VRISE are treated independently in the literature, although virtual reality is increasingly considered an option to replace PCs at the workplace, which encourages us to consider them all at once. We emphasize the context of office-like tasks in VR, gathering 57 articles meeting our inclusion/exclusion criteria. Cybersickness symptoms, influenced by fifty factors, could prevent workers from using VR. It is studied but requires more research to reach a theoretical consensus. VR can lead to more visual fatigue than other screen uses, influenced by fifteen factors, mainly due to vergence-accommodation conflicts. This side effect requires more testing and clarification on how it differs from cybersickness. VR can provoke muscle fatigue and musculoskeletal discomfort, influenced by fifteen factors, depending on tasks and interactions. VR could lead to acute stress due to technostress, task difficulty, time pressure, and public speaking. VR also potentially leads to mental overload, mainly due to task load, time pressure, and intrinsically due interaction and interface of the virtual environment. We propose a research agenda to tackle VR ergonomics and risks issues at the workplace.

“…The QDCC simulation is performed in the optical software of LightTools, and the u values corresponding to high LCE and high OD are obtained according to Equation (2). This can be used to determine the two key parameters about QD concentration and color conversion layer thickness of the red and green sub-pixels.…”

“…Green and healthy display technologies are therefore highly demanded. Currently, the visual damage on the human eye is mainly attributed by the high‐energy and short‐wave blue spectrum of the three primary colors in mainstream display devices 1,2 . However, simply cutting or reducing the blue light part is not an appropriate approach, because it easily causes serious color deviation or display distortion.…”

Quantum‐dot (QD) color conversion (QDCC) has the inherent advantages of high color purity and adjustable spectral peak, and spectral symmetry, which is favorable to healthy displays. In this paper, a theoretical design for QDCC white balance in healthy displays is proposed to achieve both high light conversion efficiency (LCE) and low blue light intensity (BLI). Based on the defined logical channels for QDCC model and the optimal criterion of the QD's dosage factor (DoF), the key design parameters of the red and green QDCC sub‐pixels are first obtained, including the QD concentration and the color conversion layer thickness. Then, according to the requirements of three‐primary‐color flux for white‐balanced display, the luminous area of three‐primary‐color sub‐pixels can be adjusted to achieve the white balance of the healthy display. Finally, by combining the above theoretical analysis and design approach, a theoretical formula is recommended for white‐balanced healthy displays with high luminous efficiency and low BLI. The white balance method is verified by theoretical derivation and optical simulation. Results show that the method can not only guide the structural design of the QDCC from the theoretical level but also ensure high LCE and low BLI for three‐primary‐color sub‐pixels. The target white balance can be well achieved by adjusting the area ratio of three‐primary‐color sub‐pixels to 3.94:5.06:1, and the color coordinates and the color temperature are (0.313, 0.3206) and 6552 K, respectively. This study provides a useful exploration of QDCC white balance design for next‐generation healthy displays with high conversion efficiency and low BLI.

“…With a high and very high level of physiological labor intensity, the annual increase in the risk of CFS increases by 2 and 4 times [3]. Programs for improving working conditions should include a section on minimizing the risks of a permanent lack of rest among workers, including regulation of the physiological intensity of work and options for "time protection" from harmful environmental factors [6].…”

There is a growing need to prevent visual fatigue of personal computer users due to the widespreaduse of computer technology. The purpose of the work is the analysis and development on the basisof the created software and hardware complex of the optimal mode of operation and removal of fatigue,conducting a series of experiments to test the effectiveness of the proposed mode of work and rest.Conclusions: The use of microcontroller technology with a wireless interface greatly simplifiesthe component base of the developed composite electronic components and expands the possibilitiesof diagnosing human fatigue. The proposed software makes this procedure accessible and easy formost diagnostic operators in the world.
